Service
API Development & Integration
Connect your applications, partners and data so information flows automatically and reliably, without manual exports, duplicate entry or fragile point-to-point scripts.
What this service covers
Integration is where digital projects succeed or stall
Most organisations run many systems: CRM, ERP, finance, e-commerce, help desk and more. Value is lost when they do not talk to each other. Staff copy data by hand, reports disagree and customers receive inconsistent information.
We design and build APIs and integrations that are secure, documented and observable. Whether you need to expose your services to partners, connect a new platform to existing systems or replace a tangle of scripts, we focus on reliability and maintainability.
Typical scope includes
- Public and partner-facing API design
- Internal APIs for web and mobile applications
- Third-party SaaS and payment integrations
- ERP, CRM and accounting system integration
- Event-driven data synchronisation and webhooks
Business problems
Challenges we help you solve
Manual data transfer
Teams export and import spreadsheets between systems, introducing delays and errors.
Fragile point-to-point scripts
Undocumented scripts fail silently and only one person knows how they work.
Partner onboarding friction
Each partner integration is custom-built and time-consuming.
No single view of data
Customer and order information differs between systems, undermining trust in reports.
Capabilities
What’s included
API design
Consistent, versioned REST and GraphQL APIs designed around clear resources and use cases.
System integration
Connectors for SaaS platforms, ERPs, CRMs, payment providers and logistics services.
Event-driven sync
Webhooks and message queues that propagate changes as they happen.
API security
Authentication, authorisation, rate limiting and input validation.
Documentation and portals
Reference documentation, examples and sandboxes for developers.
Monitoring and alerting
Visibility of failed calls, latency and data mismatches with automated retries.
How the engagement works
Working together
Integration projects begin with mapping data ownership; the code comes after the agreements.
- Integration discovery to map systems, data owners and flows
- Interface contracts agreed before development
- Incremental delivery, one integration flow at a time
- Runbooks and monitoring handed over with each flow

Expected benefits
Operational benefits to expect
Benefits vary by organisation and starting point; these are the improvements this service is designed to support.
Less manual work
Automated data flows remove repetitive copying between systems.

Frequently asked questions
Answers to the questions we hear most often. If yours is not covered here, our team is happy to talk it through.
Often, yes, through database views, file exchanges, email parsing or, as a last resort, interface automation. We recommend the most reliable option available and explain the trade-offs.
Integration platforms speed up common connections; custom services offer more control for complex logic or high volumes. Many solutions combine both, and we help you choose.
We define a source of truth for each entity, use idempotent processing and retries, and build reconciliation checks that flag discrepancies for review.
Yes. APIs we build include OpenAPI specifications, usage examples and, where appropriate, a developer portal.
